To all whom t may concern.'

Be it known that I, WILHELM HAMANN, painter, subject of the King of Prussia, residing at Charlottenburg, Hertzstrasse 7, Prussia, Germany, have invented certain new and useful Improvements in Clasps, of which the following is a specification.

The present invention relates to a clasp for holding woven or other soft fabrics, such as hose, curtains, hangings and the like by means of two loops engaging crosswise in each other.

The essential feature of the present invention consists in the fact that these loops are of an oblong, oval or similar shape, which hereinafter shall be called pear-shaped, and that the said loops are corrugated. Owing to these features it is possible to push the two loops, which may be considered as turned around an angle of 180O relatively to each other, in such a manner crosswise in each other, that the smaller bend of the one loop will enter the larger bend of the other loop, while the corrugated parts engage in such a manner beside and around each other, that, when seen from one side, appear as if partly twisted around each other, similar to a cord.

The object of such arrangement of the clasp is that the material to be gripped, bears on as large a surface as possible or is gripped over a large surface. This will, on the one hand, afford an absolutely secure grip without the material being too severely worn, on the other hand allow of an easy opening and closing of the clasp, and thus of an easy loosening and tightening or gripping of the material.

In the hitherto known devices, in which likewise loops engaging crosswise in each other were employed, the hereinbefore mentioned advantages are not found to the same extent. All clasps of this kind hitherto disclosed grip the material only with a comparatively small part of the circumference of the clasping members, wherefrom an extraordinarily high strain on the material and a rapid wear of the latter results, beside the fact, that the detaching and gripping of the material requires amuch more complicated manipulation than with the clasp according to the present invention.

ln the accompanying drawing an embodiment of the present invention is exemplified.

Figures l and 2 are the one loop a in front and side elevation, respectively.

Figs. 3 and 4t are likewise front and side elevations respectively, but of ythe other loop 7;.

Figs. 5 and 6 are front and side elevations respectively of the two loops a and b in closed position.

Figs. 7 and 8 are front and side elevations respectively of the complete clasp with the material clasped in it.

Fig. 9 is a side elevation of the clasp in an opened position.

In the drawing the one loop is marked a, the other, co-acting loop Each of these loops is attached to a stem, consisting of a strip of sheet metal or the like, the loop a to the stem c, the loop Z1 to the stem l respectively. The two stems are positively coupled together by a part c, so that when the part e is moved, the two loops a and b are swung relatively to each other, as this is indicated in Fig. 9. The loops with their stems are, as evident from the drawing, pivotally hinged to the respective part e. The operation of the clasp is easily comprehensible with reference to the drawing.

In an opened position, as shown in Fig. 9, the material to be gripped is placed between the two loops, which are thereupon closed together, the smaller bend of the one loop thereby engaging through the larger bend of the other loop. When the part c is turned upward, as indicated by dot-and-dash lines in Fig. 9 the loops engage crosswise in each other, and the respective material is clasped or gripped between them, as shown in Figs. 7 and 8.

I claim:

, l. A clasp comprising a support having two inter-engaging loops, one of said loops being formed with an enlarged portion at one end and a smaller portion at the other end, and the other loop being reversely formed, said loops being fashioned in serpentine configuration so that the smaller portion of the reversely formed loop may enter the enlarged portion of the other loop, and the smaller portion of the last mentioned loop may enter the enlarged portion of the reversely formed loop for fastening the two loops together and to form a plurality of engaging surfaces along the sides of the clasp and at either end thereof for confining a fabric therebetween.

2. A clasp comprising a support having two interengaging loops, one of said. loops being formed with an enlarged portion at lio one encl and a smaller portion at the other end, and the other loop being reversely formed7 said loops being faShionecl/in sei'- pentine configuration so that the smaller portion of the inversely formed loop may entei the enlarged portion of the othei` loop, and the enla-ller poition of the last mentioned loop may enter the enlarged portion of the reveisely folnecl loop for fastening the t-Wo loops togetheiq and to forni a plni'ality vof engaging surfaces along the sides of the olasp and at in end theieof for confining a fabric therebetween, said reveisely rformed Vloop "having ahool formed thereon 1n which the upper portion of the other loop is lel5 ceivecl for confining the fabric between the vloops at theii1 upper eflges.Y

ln' testimony whereof l have affixed my Signature in presence of two Witnesses.
